The specific embodiment

A kind of embodiment of hoisting crane of good stability, in Fig. 3 ~ 14, the mobile dolly that arranges is shown in Fig. 3,4,5 on the girder of this hoisting crane, the below of the trolley frame 1 of dolly is hung and is provided with suspender 3, suspender 3 has a crossbeam 4, and crossbeam 4 is horizontally installed on the below of trolley frame 1, and the top of crossbeam 4 is rotated and is provided with movable pulley 10, be arranged with steel rope between the fixed pulley that arranges on this movable pulley 10 and the trolley frame 1, the steel rope here hangs suspender the below that is located at trolley frame 1.All be to realize being not described in detail in this being connected between the two by the steel rope of winding between the reel of the movable pulley of suspender and trolley frame basically between the suspender of hoisting crane and the trolley frame.

The outer peripheral face that the both ends of crossbeam 4 are provided with 8, two large guide wheels 8 of large guide wheel protrudes respectively the end face with the corresponding end of crossbeam 4, and the axially parallel of two large guide wheels 8 is all perpendicular to the bearing of trend of crossbeam.Be provided with little guide wheel 9 in the both sides of crossbeam 4, little guide wheel 9 always has eight, and wherein four are in crossbeam 4 one end places, and other four are in crossbeam 4 other end places, and, four sides that are in crossbeam 4 wherein, in addition, four other sides that are in crossbeam 4.The axis of each little guide wheel 9 is all parallel and be parallel to the bearing of trend of crossbeam 4.Be in crossbeam 4 one ends and be in two little guide wheels 9 of crossbeam the same side and a top that is in crossbeam 4, another is in the bottom of crossbeam 4.

Be arranged with guide frame 2 in the outside of suspender 3, the guide frame 2 here be square tubular framework, that is to say that this guide frame 2 is the square hollow structures that surrounded by several shaped steel, be equipped with the angle steel of gaining in strength at the lateral surface of guide frame 2.The upper end of guide frame 2 is fixedly installed flange, and guide frame 2 is fixed on the bottom of trolley frame 1 by the flange that arranges on it.

Two medial surfaces at the both ends that correspond to crossbeam 4 of guide frame 2 are provided with and are respectively arranged with pair of guide rails pair, two guide rails 6 that pair of guide rails is right are oppositely arranged respectively and roll spacing the cooperation with four little guide wheels of crossbeam corresponding end, one of them guide rail rolls with two that are in crossbeam one side little guide wheels and cooperates, another guide rail rolls with two that are in the crossbeam opposite side little guide wheels and cooperates, and two guide rails are to cooperating spacing on direction on the horizontal surface of realization crossbeam.

Two medial surfaces at the two ends that correspond to crossbeam 4 of guide frame 2 are respectively arranged with a limit guide rail 7, two limit guide rail 7 are in respectively two large guide wheels 8 rolling cooperations at crossbeam 4 two ends, prevent the motion of crossbeam 4 on its bearing of trend, realize spacing on another direction on the horizontal surface of crossbeam.Thereby so that suspender any swing can not occur in the process that rises or descend.

Here owing to will rolling with limit track, large guide wheel cooperate, so its outer peripheral face protrudes respectively the end face with the corresponding end of crossbeam 4, this is a necessary condition, that is to say, cooperate as long as large guide wheel can roll with limit track, the outer peripheral face of large guide wheel is also with regard to the end face of protrusion with the corresponding end of crossbeam 4.

The guide rail of the guide wheel centering in the present embodiment is to be formed by the H shaped steel that is weldingly fixed on the guide frame, and limit guide rail is formed by channel-section steel.

Guide frame in the present embodiment is square tubular framework, also can be for other shapes.

Guide frame in the present embodiment is fixed on the trolley frame by flange, also can directly be weldingly fixed on the trolley frame.

Little guide wheel in the present embodiment is eight, also can be four, and at this moment, the guide wheel that is in crossbeam one end just is two both sides that are in respectively crossbeam, one of a side.Certainly, the number of large guide wheel and little guide wheel all only is confined to disclosed number in the present embodiment, and those skilled in the art can change the number of large guide wheel and little guide wheel as required, to satisfy the demand of stable guiding.
